Here is an older book found at Google Books which appears to have information about #107 Andrew Neill and #108 John Neale from our Unity list.
In this book is noted a marriage between Andrew Neal and Catherine [Furbish], the daughter of William Furbish. We know William Furbish was one of the Scots from the ship Unity.
Take a look and see if this may be your ancestor.
